【摘要】：經(jīng)濟活動在空間上的變遷表現(xiàn)為集聚或分散,經(jīng)濟活動在時間上的變化表現(xiàn)為增長或衰退。集聚和增長是經(jīng)濟發(fā)展在時空演化過程中最顯著的特征,二者緊密聯(lián)系,相互促進、相互影響。然而,長時間以來,經(jīng)濟學界一直將集聚和經(jīng)濟增長的研究相分離,沒有形成一個系統(tǒng)的理論,關于集聚的研究缺乏經(jīng)濟增長的背景而顯得單薄,關于增長的研究缺乏集聚的貢獻而顯得缺憾。直到新經(jīng)濟地理學的出現(xiàn),才打破了二者長期以來的獨立分析的狀態(tài),集聚和經(jīng)濟增長開始納入同一分析框架和體系當中。在此之后,眾多學者開始從理論和實證角度對集聚和經(jīng)濟增長的關系進行了廣泛而深入的研究,絕大部分研究成果表明:集聚與經(jīng)濟增長之間存在正相關的關系,即集聚能夠促進經(jīng)濟增長。城市是人口和經(jīng)濟活動集聚的某個空間范圍和載體,城市集聚是所有集聚類型中的最高形態(tài),因為城市集聚包含了人口集聚、要素集聚、產(chǎn)業(yè)集聚等等。當城市集聚產(chǎn)生之后,又是什么機制在推動著城市經(jīng)濟的發(fā)展或者是區(qū)域經(jīng)濟的增長。通過對相關文獻和理論進行梳理,厘清城市化、城市集聚、經(jīng)濟增長之間聯(lián)系,試圖從市場機制和非市場機制兩個層面來推導城市集聚促進經(jīng)濟增長的作用路徑。市場機制主要是指城市集聚通過范圍經(jīng)濟和規(guī)模經(jīng)濟來實現(xiàn)報酬遞增,非市場機制主要是指城市集聚通過知識溢出效應和消費偏好溢出效應來實現(xiàn)報酬遞增,在二者的共同作用下,城市集聚促進了經(jīng)濟的增長。長江中游城市群是2015年國務院批復的跨區(qū)域國家級城市群,作為中部崛起戰(zhàn)略的重要支撐,國家明確對其戰(zhàn)略定位為:中國經(jīng)濟新增長極。但是,通過對發(fā)展現(xiàn)狀的描述發(fā)現(xiàn):與我國長三角、珠三角、京津冀城市群相比,長江中游城市群的城市集聚水平和經(jīng)濟發(fā)展水平整體較低。在實證研究中,以勞動生產(chǎn)率和就業(yè)密度分別作為經(jīng)濟增長和城市集聚的代理變量,利用城市群內(nèi)31個城市的10年面板數(shù)據(jù)進行多元回歸,實證結果表明:長江中游城市群城市集聚能夠促進經(jīng)濟增長,但整體集聚水平不高,對經(jīng)濟增長的促進作用不明顯。
[Abstract]:The change of economic activity in space is agglomeration or dispersion, and the change of economic activity in time is growth or decline.Agglomeration and growth are the most remarkable characteristics of economic development in the evolution of time and space. They are closely related, promote and influence each other.However, for a long time, the economic circles have separated the study of agglomeration from the study of economic growth, and have not formed a systematic theory. The research on agglomeration lacks the background of economic growth and appears to be thin.The research on growth lacks the contribution of agglomeration.It was not until the appearance of new economic geography that they broke the state of independent analysis for a long time. Agglomeration and economic growth began to be brought into the same analytical framework and system.After that, many scholars began to conduct extensive and in-depth research on the relationship between agglomeration and economic growth from both theoretical and empirical perspectives. Most of the research results show that there is a positive correlation between agglomeration and economic growth.Namely agglomeration can promote economic growth.Urban agglomeration is the spatial range and carrier of population and economic agglomeration, and urban agglomeration is the highest form of all agglomeration types, because urban agglomeration includes population agglomeration, factor agglomeration, industrial agglomeration and so on.When urban agglomeration comes into being, what mechanism is promoting the development of urban economy or the growth of regional economy.Through combing the relevant literature and theory to clarify the relationship among urbanization, urban agglomeration and economic growth, this paper tries to deduce the role of urban agglomeration in promoting economic growth from the two aspects of market mechanism and non-market mechanism.Market mechanism mainly refers to urban agglomeration through scope economy and economies of scale to achieve increasing returns, non-market mechanism mainly refers to urban agglomeration through knowledge spillover effect and consumption preference spillover effect to achieve increasing returns.Under the joint action of both, urban agglomeration promotes the growth of economy.Urban agglomeration in the middle reaches of the Yangtze River is a cross-regional state-level urban agglomeration approved by the State Council in 2015. As an important support of the strategy of rising up of the middle part of the Yangtze River, the state has clearly defined its strategic position as: the new economic growth pole of China.However, it is found that compared with the Yangtze River Delta, the Pearl River Delta and the Beijing-Tianjin-Hebei urban agglomeration, the urban agglomeration level and the economic development level in the middle reaches of the Yangtze River are lower.In the empirical study, the labor productivity and employment density are taken as the proxy variables of economic growth and urban agglomeration, respectively, using the 10-year panel data of 31 cities in the urban agglomeration to carry out multivariate regression.The empirical results show that urban agglomeration in the middle reaches of the Yangtze River can promote economic growth, but the overall agglomeration level is not high, and the promoting effect on economic growth is not obvious.
